PWM oscillator frequency setting
Insert a capacitor between this pin and ground.
Control voltage input. The PWMIN pin must be set
low when this pin is to be used for voltage control.
Shared function pin: Constraint protection circuit
operating time setting and initial reset pulse setting.
Insert a capacitor between this pin and ground.
When the protection circuit is not to be used, connect
a resistor (150kΩ) and a capacitor (4700pF) in parallel
between this pin and ground.
Start/Stop control
A low-level input sets the IC to start mode, and a high
level input sets it to stop mode.
PWM pulse input
A low-level input specifies the output drive state, and
a high-level or open input specifies the output off
state.
When using this pin for output control, connect the
VCTL pin to the VREG pin and insert a 2kΩ resistor
between the TOC pin and ground.
